The National Oceanic and Atmospheric Administration’s Office of Aquaculture this week released its new five-year plan for building a great US aquaculture industry -- but there is a major flaw. It leaves out one of today's most promising aquaculture growth sectors, one in which the US already has an advantage.

Recirculating aquaculture system technology, or RAS as it more commonly known, is arguably the hottest aquaculture trend at the moment.

Startups around the world are investing in the technology to allow them to grow salmon, shrimp and other species on land and close to consumer markets in an effort to take advantage of the booming demand for seafood, locally grown foods, and to mitigate climate change impacts on traditional fish farming in the process.
